White sturgeon, Acipenser transmontanus, were reared in the presence (gravel) or absence (bare) of substrate at either 13.5 or 17.5°C during the yolk sac phase. Fish reared in gravel were transferred to bare tanks at emergence from substrate and reared to 46 days post hatch (dph). At any given dph or Accumulated Thermal Unit (ATU), the fish reared in gravel were significantly larger and survival was higher than those reared without substrate at both temperatures (T). Cumulative survival was lower at high T and was 20% greater in gravel-reared larvae in both T. Yolk absorption rate did not vary between bare and gravel, but was significantly greater at high T. Yolk absorption efficiency was greatest in gravel-reared fish, but did not vary with T. Liver histology indicated that fish reared in gravel had significantly greater quantity of lipid during the yolk sac phase. In a second experiment, yolk sac larvae were reared in the presence (gravel or bio-spheres) or absence (bare) of substrate at 13.5°C and respirometry used to measure both routine and maximum metabolic rate for assessing metabolic scope. Larvae reared in gravel had significantly greater metabolic scope, and whole body glycogen was significantly greater in larvae reared in both substrates at 8 dph indicating that substrate rearing may provide a greater capacity of growth and development at a time of intense organogenesis. Histological analysis of the liver showed greater lipid and glycogen in larvae reared in substrate. These findings suggest that larvae reared without substrate may divert more of their energy to non-growth related processes, such as swimming activity, which was observed but not quantified. Thus, larvae reared without substrate may be at a significant physiological disadvantage, leaving less energy for growth and development. --P. i.

Modern North American sturgeons and paddlefish are the result of 100 million years of evolution. Once an integral part of aboriginal culture, their numbers were decimated by overfishing and habitat destruction during the past two centuries. This book details the extensive science aimed at helping these remarkable species recover from the brink of extinction, and describes the historical, biological, and ecological importance of North American sturgeon and paddlefish. The text is enhanced by photographs and detailed line drawings. This comprehensive volume will be an invaluable resource for researchers, educators, and consultants, in academic and government settings, who work to further scientific understanding of these fishes. No other single compilation has documented current information in such detail.

Based on a workshop held at the Santa Fe Institute in June, 1990, this book explores structure in organisms—both physical and dynamical—and presents the current status of the search for natural pathways, principles of organization, and the theory of design for organisms. Topics discussed include dynamical systems analysis; the pathways of evolution; development, physiology, and functional morphology; and the principles of dynamical change in connectivity within the networks of processes.

It is a tribute to the vigour of research and development in aquaculture that we are able, in a relatively short time, to provide readers with a second volume in this series, which has such a diversity of high calibre research and developments to report. That the first volume was so well received has been a source of great satisfaction to the editors and supported their conviction as to the need for links to join the research laboratory to the fish farm by making current research available to a wider range of potential users.
